WHAT OTHERS HAVE SAID

John A.T. Robinson
"Moreover, if Matt. 2 2.7 did reflect the happenings of 70 one might expect that it would make a distinction that features in other post eventum 'visions', namely, that while the walls of the city were thrown down, it was the temple that perished by fire. Thus the Jewish apocalypse II Baruch clearly reflects the fall of Jerusalem to the Romans, though it purports to be the announcement to the prophet Baruch of a coming Chaldean invasion. It recognizes that the city and the temple suffered separate fates:

We have overthrown the wall of Zion and we have burnt the place of the mighty God (7.1). [I.e. the temple. For this sense, cf. II Mace. 5.17-20; John 11.48; Acts 6.14; 21.28; etc.]

They delivered ... to the enemy the overthrown wall, and plundered the house, and burnt the temple (80.3).

If one really wants to see what ex eventu prophecy looks like,  one should turn to the so-called Sibylline Oracles (4.125-7):

And a Roman leader shall come to Syria, who shall burn down Solyma's [Jerusalem's] temple with fire, and therewith slay many men, and shall waste the great land of the Jews with its broad way. [Tr. R. H. Charles, The Apocrypha and Pseudepigrapha of the Old Testament II, Oxford 1913,395.]  (Redating New Testament (1976) Chapter Two: The Significance of 70)

Written shortly after AD 70?

"A pseudepigraphal work (not in any canon of scripture), whose primary theme is whether or not God's relationship with man is just. The book is also called The Syriac Apocalypse of Baruch because it was preserved only in the 6th-century Syriac Vulgate. It was originally composed in Hebrew and ascribed to Baruch, a popular legendary figure among Hellenistic Jews"

"The work appears to have been written after the fall of Jerusalem in AD 70, like 4 Ezra, an apocalypse with which it has a number of points in common, and the Paraleipomena Jeremiou in which Baruch also is an important figure. The work tries to give an answer to the burning question why God allowed his temple to be destroyed. The answer is that God himself sent his angels to destroy his sanctuary and that the time of this tribulation will be short. In other words, the destruction of the temple is God's final act before the day of judgment on which the enemies of Israel will be punished and God's people will be vindicated." (A. F. J. Klijn, Outside the Old Testament, p. 194)

"Kneucker, Marshall, and several other recent critics, however, place its composition after the capture of Jerusalem by Titus, holding that the "strange nation" of iv. 3 ("give not thine honor . . . to a strange nation") refers to the Christians, and relates to a time when the antagonism between Judaism and Christianity had become pronounced."
